General Description

The LVT162245 and LVTH162245 contains sixteen noninverting bidirectional buffers with 3-STATE outputs and is intended for bus oriented applications. The device is byte controlled. Each byte has separate control inputs which can be shorted together for full 16-bit operation. The T/R inputs determine the direction of data flow through the device. The OE inputs disable both the A and B ports by placing them in a high impedance state.

Features

■ Input and output interface capability to systems at 5V VCC

■ Bushold data inputs eliminate the need for external pullup resistors to hold unused inputs (74LVTH162245), also available without bushold feature (74LVT162245).

■ Live insertion/extraction permitted

■ Power Up/Down high impedance provides glitch-free bus loading

■ A Port outputs include equivalent series resistance of 25Ω making external termination resistors unnecessary and reducing overshoot and undershoot

■ A Port outputs source/sink ±12 mA. B Port outputs source/sink -32 mA/+64 mA

■ Functionally compatible with the 74 series 162245

■ Latch-up performance exceeds 500 mA

■ ESD performance:

Human-body model > 2000V

Machine model > 200V

Charged-device model > 1000V

■ Also packaged in plastic Fine Pitch Ball Grid Array (FBGA)
